Despite the minimal decor and burgers, don't expect fast food. On the upside, this means all the meat dishes are cooked to order and succulent. The downside is that it takes a while, even when there are no other customers. When its busy, its glacial. I admire that they don't take shortcuts, but I have a feeling they could be a lot more efficient without affecting food quality.
The employees don't seem very experienced, but they try to make up for it by doing whatever they can for you.
